# Triggering Events While Typing

> *You're reading the documentation of an older/legacy version, Text Animator 1.X.  To read the latest version, please visit this page instead* [2.X (EN)](https://docs.febucci.com/text-animator-unity/2.x/)*. How to update:* [Upgrading from 1.X to 2.X](/text-animator-unity/2.x/other/changelog/upgrading-from-1.x-to-2.x.md)

***

Events are special tags that let you send messages (string) to any listener script, once the typewriter has reached a specific part of the text. *(For this reason, events work only if the typewriter is enabled)*

***

## Overview

You can write events in your text by using rich text tags.

### Formatting

Event's messages are preceded by a question mark, like this: `<?eventMessage>`.

**Example:** To call an event named 'shakeCamera', write: `<?shakeCamera>`

* 👍🏻 An event can have any kind of tag, including built-in effect's ones.
* ⚠️ Events are case sensitive. Writing `<?camshake>` is not the same as writing `<?camShake>`

***

## Listening to events

The scripts that you want listen to TextAnimator events/messages must subscribe to the `onEvent` callback, inside the `TextAnimator` class. (Scripting Api)

Example:

```csharp

//Inside your script

public TextAnimator textAnimator;

//Manage the event subscription

private void Awake()
{
    textAnimator.onEvent += OnEvent;
}

private void OnDestroy()
{
    textAnimator.onEvent -= OnEvent;
}

//Do things based on messages
void OnEvent(string message)
{
    switch (message)
    {
        case "something":
            //do something
            break;
    }
}
```

👍🏻 Note how the "message" string has no ‘<‘, ‘?’ and ‘>’ characters, but only contains the message.
